{"version":"1.0","type":"rich","title":"Choropleth Map","description":"This choropleth map colors countries by their economy classification using an ordinal color scale with a spectral scheme. The geographic data comes from the world-atlas TopoJSON dataset, which is processed with topojson.feature and joined to TSV metadata. A natural Earth projection renders the map via d3.geoPath, while d3.zoom enables panning and zooming. Hovering highlights countries in red, and a custom color legend displays the color scale with circles and text labels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3cf3057b3a9f4ec39a655f201cd5436e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
